Safety, tolerability, and best practices Animal studies show BPC 157 peptide to have a favorable safety signal
- Whole-body imaging of even low-activity levels of Lu-177 using a new "Low Activity mode." - Immediate post-administration visualization of organ-specific uptake, such as in the salivary glands (which is relevant since salivary glands can be affected in these therapies)
